L1. BTU T-SHIRT
Crafted with a loose, 90s-inspired oversized silhouette, our Basics T-shirt boasts slightly amplified proportions and dropped shoulders for a laid-back fit. Made from premium 320 gsm cotton jersey, it features our “SEVEN LAYER” insignia stamped on the back. These are the ultimate T-shirts you’ll ever own. Take your normal size.
Details
THE BTU SYSTEM
The system includes (but not limited to) lightweight down jackets, water-resistant rain shells, nylon windbreakers, hoodies, sweaters, sweatpants, t-shirts, shorts, and socks. While the BTU collection is made with the same high standards of manufacturing and premium materials as SEVEN LAYER's technical apparel, it’s primarily geared toward everyday wear. The focus is on comfort, aesthetics, and lifestyle appeal, rather than performance. As such, BTU garments may not include advanced features like weatherproofing or breathability, which are found in the brand’s ATU (Advanced Training Uniform) system designed for technical activities such as trekking or mountaineering.
SIZING ADVICE
We suggest you take your normal fit. For existing customers who purchased an OASIS T-Shirt these new BTU T-shirts have been down sized by one size so we suggest to take your normal size.
